And Mr Callahan, who teaches at Lowell High School, later shared the entire document online, making us love him even more.

Here’s what he had to say.

“Hello, internet! I hope this comes in handy! I’m happy to offer this to the world for free, but if you’re feeling philanthropic today, please consider two options that would greatly help the students of Lowell, Massachusetts. The Lowell String Project, and Mrs. Bauer’s Donors Choose page, stay up, Mr. Callahan.”
